Comment 3 for bug 1526485

I have some questions about this spec, if someone still work on it, maybe we could have a discussion.

Q1: Which multicast mode is considered? Any Source Multicast or Source Specific Multicast.
Q2: How many group address will be used? For example, One user image uses one group address(or channel).
Q3: How to control the receiver, not all the baremetal nodes can receive the user image.
Q4: Multicast isn't reliable, how about RMTP?
